1. Before installation, check whether the nominal voltage of
the battery pack is suitable for the UPS: the voltage
mentioned on the label on the battery drawer of the UPS
and the one on the rear panel of the battery extension pack
(36 Vdc or 72 Vdc) should match.
2. Check if the battery breaker on the rear side of the
battery pack is in the “OFF” position.
3. UPS and battery pack can be mounted together in one
set of mounting supports. (For Rack mount See 3.3.2)
4. At the rear side the UPS and battery pack can be coupled
using the coupling bracket that came with the battery pack.
5. Connect the DC connector of the battery pack to the DC
socket of the UPS (fig. 5a and 5b). You will hear a click
when the cable is properly connected. Block the DC
connector: install the small locking plate that came with
the battery pack, and fasten it with the screw provided.
6. Connect the DC connectors at the front side of the
battery pack similar to UPS (See 3.3.1 step 3).
7. Assemble the front panel: insert the two metal clamps at
the rear of the panel into the holes at the upper side of
the UPS, then click the front panel into position. Fix the
front panel with the screw provided.
8. Ensure that Battery Breaker at the rear side of the Battery
pack is turned to “ON” Position to complete installation.

NOTE
The UPS output sockets can be live as soon as the UPS is connected to the main power supply, even if
the UPS has not been switched on via the front panel.
1 Switch off your computer, and unplug it from the socket-outlet.
Fig. 3.5.2: Connecting power and load
NOTE
Grid supply is 120 Volt, 50/60 Hz,
fused (see section 3.2)
2 Disconnect the power cord from the computer (see note
below) and connect this cord to the male input socket (1, fig.
3.4a/b) at the rear of the UPS.
3 Add up the power consumption (in VA) of the appliances that
will be protected by the UPS (‘the load’) and make sure that the
resulting value does not exceed the VA output rating of the
UPS. This way you ensure that the UPS is able to supply the
required output and prevent that an overload situation will
happen.
4. Using the output cords (see note below) connect the load to
the appliance outlets (3, fig. 3.4a/b) of the unit. Spread the
loads over the appliance outlets as equally as possible. If you
use a distribution box to connect more than one appliance per
outlet, please note that the maximum AC-current rating of each
appliance outlet is 20A (3, outlets on fig. 3.4a/b).
5 Connect the mains cord of the UPS to a working, grounded AC
wall socket outlet. The green LED ‘operation’ will blink now:
mains power is available and the batteries are charging. If the
LED does not blink but illuminates continuously instead, press
keypad ‘0’ for one second.
If both LEDs ‘operation’ and ‘alarm’ blink and the beeper
sounds 1/2secs, phase and neutral are reversed at the input
of the UPS. Please read 4.4.12 and take appropriate measures.
For best results, allow the UPS to recharge the batteries during a
period of approx. 2 hours. It is acceptable to use the UPS without
first charging the battery, but the runtime may be reduced.
NOTE:
To connect UPS and loads use Cables meeting the below requirements:
Detachable UL Listed, SJT Type flexible cord with grounding type plug, maximum 14.76 ft. (4.5m) long.

runtime with the actual load
8 - LED bar ‘load’ indicates to what extent the output capacity of the UPS is used by the actual load. If
e.g. the 25% and 50% LED are on, the load exceeds 50% of the maximum load. If all
4 LEDs are on the unit operates in overload. As this is an abnormal situation the
alarm LED will blink as well.

NOTE
The unit can be used as a frequency converter: the input frequency range is 45-66Hz, the output frequency is
selectable 50/60Hz. If the unit is used as a frequency converter, the bypass function is no longer available. As a
result an audible alarm will be generated continuously (see 4.4.6). To avoid this, we advise to disable the
bypass.
WARNING!
Changing of the output frequency can cause severe damage of equipment connected to the
appliance outputs of the UPS: Be sure that the new frequency is suitable for the connected equipment!
4.2 START-UP
4.2.1 Start-up, mains available
Via front panel:
press keypad 'I' (1, fig. 4.1) briefly; LED ‘operation’ (already slowly blinking) will at first blink faster and after a few
seconds it will illuminate continuously, indicating that the unit has started up.
Via UPS monitoring software:
startup after delay, see 4.4.11 for more information. The equipment connected to the UPS can now be switched on.
The UPS will not start-up if "Phase Neutral reversal" indication is present (see section 4.4.12).
4.2.2 Start-up, mains not available
If the mains input is absent (power cord not connected, or mains failure):
Press keypad 'I' until the buzzer sounds. The LEDs ‘operation’ and ‘on battery’ will illuminate. The UPS operates on battery: it
discharges the batteries. See 4.4.4 for further details about this operating mode.
4.3 USE: NORMAL OPERATION
4.3.1 Normal operation conditions
the mains supply is present,
the UPS is on,
the load does not exceed the capacity of the UPS and
the operating temperature is below alarm level
4.3.2 No-load shutdown
If this function is activated, the UPS will switch off during a mains failure when the load is less than 5% of the maximum load.
In this way unnecessary discharging of the batteries is avoided. The unit will automatically turn on again when mains power
is restored. The default setting of the no-load shutdown function is: disabled.
The setting can be changed using the UPS monitoring software. For more information please refer to the manual that
came with the software.
If the no-load shutdown function is activated and the load is smaller than the 5% threshold, the ‘25%’ load LED will blink to
warn you that the unit will switch off during a mains failure.
4.3.3 Output frequency
At power up default enabled "Auto" frequency detection updates output frequency setting by comparing it with input
frequency. Only stable 50 or 60 Hz frequencies are valid, otherwise previous setting is kept (60 Hz at first start up). Setting
output frequency to 50 or 60 Hz with the UPS monitoring software disables the "Auto" frequency detection.
4.3.4 Switching off
Via operating panel:
Press keypad ‘0’ (2, fig. 4.1) for 1 second. If the UPS is switched off the output will always be absent for a few secon ds
to ensure that the connected equipment is able to reboot.
Using UPS monitoring software:
Shutdown after delay.
If electric isolation is required, unplug the power cord from the wall outlet.

4.4.1 Standby
The UPS output is off, but the batteries are charging, see 3.5.2 step 5
4.4.2 Normal operation
See 4.3.1.
4.4.3 On bypass
The UPS is equipped with an automatic bypass switch. This switch automatically transfers the load to the mains if the UPS is
unable to deliver the demanded output power due to overload or overtemperature.
If all 4 load LEDs illuminate, bypass operation is caused by an overload. If only green load LEDs illuminate (the red load LED is
off), bypass operation is caused by overtemperature. Take appropriate measures: reduce load and/or temperature.
The UPS will switch back to normal operation when the overload has been removed or the temperature has dropped below
alarm level.
If a power failure occurs during bypass operation, the UPS will switch to battery operation and eventually, when the
batteries are depleted, output power is lost.
The bypass function can be disabled - see 4.4.6 and 4.5 for further details.
Fail safe bypass operation: if the UPS becomes defective, the load may be switched to bypass (provided that the bypass
function was not disabled). As the status of the UPS is unknown in this situation the indications on the operating panel may
differ.
4.4.4 On battery
The UPS uses the energy stored in the batteries: see section 8 ‘Batteries - runtime’.
The runtime capacity LED bar will show the remaining runtime. The UPS will shutdown:
after the batteries have been discharged (automatic restart), or
if keypad 'O' is pressed (restart via front panel required) or
if a 'UPS shutdown' command is given by the computer (automatic restart)
Automatic restart depends on the setting of the ‘auto restart’ function:
- if set ‘on’ the UPS will automatically restart when the mains returns
- if set ‘off’ a manual restart is required, as in 4.2.1.
As default the ‘auto restart’ function is ‘enabled’. The setting can be changed using the UPS monitoring software. For
more information please refer to the manual that came with the software.
4.4.5 Battery low (end of runtime)
If during ‘on battery’ operation the 25% LED starts blinking, the batteries are nearly discharged: the remaining runtime is less
than 2 minutes (default setting, adjustable via the UPS monitoring software). Controlled shutdown of any computer
equipment is absolutely necessary at this point.
If the UPS operates at 100% load, the shutdown procedure should be completed within 2 minutes after the 'battery low'
alarm started. If only part of the output capacity of the UPS is used this period can be longer, with aged batteries this period
can be shorter.
When the batteries are fully discharged, the UPS is no longer able to power the connected equipment.
4.4.6 Bypass out of limits
The mains voltage or mains frequency are outside bypass input tolerance but inside UPS input tolerance (see section 8).
Bypass operation is inhibited: if for whatever reason the UPS is not able to deliver the required output, output power is lost. If
the input frequency is often out of tolerance – during which bypass operation is inhibited and an alarm is generated – it may
be useful to disable the bypass function after which the unit operates as a UPS without automatic bypass switch. See 4.5.
4.4.7 Overload
The demanded power exceeds the normal capacity of the UPS. The alarm occurs when the load is > 100%. If the load
exceeds 150% the UPS will immediately switch to bypass, assuming that the conditions for a transfer to bypass are fulfilled.
If an overload condition between 110-150% persists, the UPS will also switch to bypass operation.
During an overload the UPS may automatically switch off within a few minutes (load dependent) and output power is lost:
if a transfer to bypass is inhibited (see 4.4.6), or

NOTE
Use standard Low Voltage Cable in accordance with National and local regulations.
if the bypass function has been disabled (see 4.5), or
if the UPS operates on battery (see 4.4.4).
To avoid these problems, be absolutely certain that the power demands of the protected equipment are within the limits of
the UPS.
4.4.8 Battery bad
Either the batteries are almost chemically worn out or the battery wiring, including the battery fuse, is faulty. If the batteries
are aged, they must be replaced as soon as possible to ensure full protection for your equipment. Perhaps the 'battery bad'
alarm occurs after a test which you started immediately after installation or after a power failure. In this case the alarm may
be incorrect as the batteries have been (partly) discharged during transport or storage / during the power failure. Allow the
UPS to recharge the batteries. See also 4.6.
4.4.9 General alarm
‘General alarm’ comprises a group of alarms; the buzzer behaviour indicates which alarm is active:
4.4.10 Shutdown pending
The UPS monitoring software allows you to switch the UPS into standby mode after a programmable delay time. During
countdown the ‘operation’ LED will blink 2x per second and the buzzer will beep every 5 seconds.
4.4.11 Startup pending
The UPS monitoring software allows you to start up UPS after a programmable delay time. During this delay time the
‘operation’ LED will blink 2x per second.
4.4.12 P-N (Phase-Neutral) reversal
If the P-N reversal indication is enabled, the UPS will indicate whether the voltage between Neutral and Earth (Ground) at the
UPS input exceeds a certain voltage (i.e. Phase and Neutral at the UPS input are reversed in an earthed/grounded Neutral
system). In this potentially unsafe situation both LEDs ‘operation’ and ‘alarm’ will blink fast and the buzzer will sound.
Reversing the mains plug will prevent this unsafe situation and will cancel the alarm. In case of non-earthed/grounded
Neutral system this indication should be disabled.
The default setting of the P-N reversal indication is: enabled.
Changing of the setting is described in section 4.5.
4.4.13 REPO (Remote External Power Off)
REPO can be used for remotely shut down the UPS by opening the cable link provided in the connector at the rear side of
the UPS. The REPO functionality can be disabled by Configuration tool. (Default: Enabled)
For remote connection, remove the cable link in the connector and connect to a cable with a switch. The switch should
be of Normally Closed type for normal operation. When the contact is opened, UPS will shut down.
Entire Front panel LEDS of the UPS will blink continuously and buzzer beeps when the UPS shut down using REPO
function.
To restart the UPS, the loop should be closed by either closing the remote Switch or placing the cable link in the REPO
connector and the “ON” “button in the UPS front panel is pressed.

NOTE
If the test is started manually immediately after installation or after a power failure, the UPS may
generate a false 'battery bad' alarm as the batteries have been (partly) discharged during
transport/storage or during the power failure.
NOTE
When executing a deep battery test the available runtime in case of mains failure may be shorter than
normal. Don’t execute this test if reduced battery runtime is not acceptable.
4.6 BATTERY MANAGEMENT
Maximum battery life and reliability are obtained by the following features:
Quick battery test
The quick battery test checks whether the batteries and their wiring are healthy. If a quick battery test shows that the
batteries are close to being worn out, a 'battery bad' alarm will be generated (see 4.4.8). Batteries have to be replaced as
soon as possible.
Automatic battery test
The VH Series UPS conducts periodic automatic battery tests:
5 hours after manual switch-on
5 hours after return of mains following any power failure, and
30 days from the last battery test
Manual battery test
A quick battery test can be initiated manually
- either via the front panel, by pressing pushbutton ‘I’ for 5 seconds during normal operation,
- or via UPS monitoring software. For details please refer to the manual of your software.
Deep battery test
A deep battery test, to be initiated through the UPS monitoring software, checks the actual battery capacity in order to
ensure accurate runtime prediction. During a deep battery test the batteries will be discharged.
Temperature compensated battery charging
This feature adjusts the battery charge voltage according to the ambient temperature. As a result poor charging of the
batteries under low temperature conditions and overcharging of the batteries under high temperature conditions are
avoided.
Load dependent battery-end-voltage
The allowable final battery voltage depends on the discharge current: the higher the current, the lower the 'end-ofdischarge' battery voltage. In this way maximum battery capacity is obtained without over-discharging. Over-discharging
would result in shortened service life and failure to recover normal capacity.
Automatic boost charge
This feature reduces the battery recharge time considerably: totally depleted batteries will be recharged to 90% in approx.
3.0 hours, provided that discharging took place at 100% load.
